BMPRQVEMEN'E' i-N THE FERMENTA'HON AN o PURiFiGATIQN or onenmc su'asrmcss.

I who achedclo ref to in these Potent ma 1 puncture-ems.

Currents of atmospheric air or other gases, impelledthrough organic substances that are subjected to a fermentation, purification, or curing are of incalculable benefit in these processes, in which an elimination oi the albuminous parts, their coa mlatiou, or an alteration of the nitrogenous deleterious matter is required, and'patents for improvements in such processes are secui'cdhy me August 6, 1867 and August 3, 1869.

in open vessels or receptacles, or under ordinary atmospheric pressure, the action is sometimes slow, so that the currents of air or gases ha-ve tobe crnitinued for a longtime, the temperature. to be unduly raised, ($60., or the action on some substances is altogether in difl'erent.

The requisite chemical action is out of proportion intensified by conducting under a higher pressure the process of fermentation or germination, the purification, preserving, or improving oi'organic substances, by currents of air or other gases.intended to act principally upon the nitrogenous parts of said organic substances.

This increased intensity in the chemical action secures advantages in time, labor, superiority of product, duo. For instance, impure liquids of high saccharine density, and other fluids that resist the action of currents of air under ordinaryatmospherio pressure, are

readily acted upon and purified under increased press- The kinds of gases, varying with the purpose in view, are principally oxygen, ozone, carbonic, sulphurcus, and phosphorous acids, and employed generally, though not always, in connection with atmospheric air.

The air or gases of a proper temperature and moisture are impelled into the receptacle of the "substance under treatment by suitable pumps, or other blowing apparatus, or by the pressure produced in'the genera-.- tion of the gases from other combinations.

Unless generated in the same room with. the substance under treatment itself, the gases or air enter the same, if this is inn fluid state or immersed in a fluid conveniently near the hottoinot' the vessel cureccptacle, by pipes, open or perforated, or by mouthpieces or peribiated plates. v

' Currents oi finely-divided air or gases are generally ofunore chemical efliciency on organic substances than the sameor a larger amount passing through in buik. v Q

The pressure is controlled by regulating the exit of the air or gases from the receptacle, or in any other manner.

A uniform pressure may be maintained, or the intensity changed at various stages of the process, or the pressure only applied at intervals, and the kind or proportion of the gases employed may he also changed at various tiines, in which manner effects can be produced not attainable by continuous actions of currents of the same gases.

I do not claim the use of gases under pressure for the mere purpose of impregnating fluids or solids with them, as is done in the manufacture of mineral waters,

for sponging bread dough, and the like, orto form a combination of mineral substances by such agents; but

What I claim, and'desire to secure by Letters Putent, is-

The mode, to assist a fermentation or. germination, the pui'iiication of organic fluids i'rmnnitrogenons or deleterious matter,- the preservation, curing, or improving of organic substances by artificial currents of air or other gases through said substances, in close receptacles, and at a highertha-n the common atmospheric pressure, substantially as and for the purposes hereinbefore described and set forth.
